Is an example for solid state fermentation?

Examples include fermented bakery products such as bread or for the maturing of cheese. SSF is also widely used to prepare raw materials such as chocolate and coffee; typically cacao bean fermentation and coffee bean skin removal are SSF processes carried out under natural tropical conditions.

What is solid state fermentation?

Solid state fermentation (SSF) has been described as the process that takes place in a solid matrix (inert support or support/substrate) in the absence or near absence of free water (Singhania et al. 2010), but the substrate requires moisture to support the growth and metabolic activity of microorganisms (Thomas et al.

What happens during solid state fermentation?

Solid State Fermentation (SSF) is a fermentation method used by several industries like the pharmaceuticals, food, textile etc., to produce metabolites of microorganisms using solid support in place of the liquid medium. It is defined as the growth of microbes without free-flowing aqueous phase.

What is the difference between submerged and solid state fermentation?

The key difference between solid state fermentation and submerged fermentation is that solid-state fermentation involves the cultivation of microorganisms on a solid substrate with a low moisture content while submerged fermentation involves the cultivation of microorganisms in a liquid medium which has more than 95% …

Which of the following is not an example of solid state fermentation?

Which of the following is not true of solid state fermentation (SSF)? Explanation: The chances of contamination is low because of less availability of water. However, the chances of contamination are more in submerged liquid fermentation.

What are the characteristics of solid state fermentation?

SSF offers many advantages over conventional submerged fermentation (SMF) such as, simple and inexpensive substrates, elimination of the need for solubilisation of nutrient from within solid substrates, elimination of the need for rigorous control of many parameters during fermentation, product yields are mostly higher …

How long does solid state fermentation take?

The fermentation time required to produce maximum enzyme was only 3 days, compared to 6 days for submerged and liquid-surface fermentation.

Why is solid state fermentation better than submerged fermentation?

Solid State Fermentation and Its Applications With little or no free water in the fermentation bed, SSF generates higher volumetric productivity and less waste water. The extraction of products from the fermentation bed can provide more concentrated solutions than submerged fermentation for the downstream processes.

What are the advantages of solid-state fermentation?

Although less employed at an industrial level, SSF is recognized to commonly offer a series of advantages over submerged (or liquid) fermentation (SmF), such as higher yields and productivities, extended stability of products, lower production cost, lower protein breakdown (which is especially important if an enzyme is …

What are the advantages of solid state fermentation?

What is the 2 main types of fermentation?

There are two types of fermentation, alcoholic fermentation and lactic acid fermentation.

What are the applications of solid state fermentation?

Applications of Solid State Fermentation (SSF) Solid-state fermentation has emerged as a potential technology for the production of microbial products such as feed, fuel, food, industrial chemicals, and pharmaceutical products.

How big is a solid state fermentation matrix?

A solid porous matrix which can be biodegradable or not, but with a large surface area per unit volume, in the range of 103 to 106 m2/ cm3, for a ready microbial growth on the solid/gas interface.

Which is more important SSF or submerged fermentation?

SSF plays a more important role in industrial fermentation processes compared to the traditional submerged fermentation (SMF), because it resolves the problem of solid waste disposal.

What are the different types of fermentation systems?

They are classified into fermentations without agitation (tray systems and air flow systems), with occasional agitation and with continuous agitation (slow rotating drums). Rotating drum:usually a cylindrical drum mounted on its side onto rollers that support and
